Question 1

Which testing scenario evaluates a biometric system using data collected in a controlled lab environment separate from real-world conditions?

Accepted Answer

Technology evaluation

Answer

Technology evaluations test biometric algorithms using pre-collected datasets in controlled conditions, independent of operational hardware.

Question 2

What is the primary purpose of a biometric scenario evaluation?

Accepted Answer

To simulate real-world conditions using a specific system configuration

Answer

Scenario evaluations test complete biometric systems under simulated but realistic conditions to predict operational performance.

Question 3

What does throughput rate measure in biometric system testing?

Accepted Answer

The number of individuals processed per unit of time

Answer

Throughput rate measures how many individuals a biometric system can process (enroll or verify) within a defined time period.

Question 4

In biometric testing, what does 'ground truth' refer to?

Accepted Answer

The verified, authoritative identity information used to evaluate system decisions

Answer

Ground truth is the known, verified set of correct identities used as the reference standard to measure how accurately a biometric system performs.

Question 5

What is a 'wolf attack' in biometric security testing?

Accepted Answer

An attempt to find biometric samples that falsely match many identities

Answer

A wolf attack exploits a biometric system by submitting specially crafted samples designed to match a large number of stored templates, maximizing false acceptances.
